2 AC cable - Power from the mains network, supplied by the electricity company.
3 AC cable - Auxiliary power supply.
DANGER! RISK OF ELECTRIC SHOCK!
Before carrying out any operations on the unit (cleaning and maintenance performances,
connection of appliances, etc.) disconnect all power sources.
DANGER! LIVE DEVICE! RISK OF ELECTRIC SHOCK: Carry out the following steps before
system maintenance:
- Disconnect the batteries.
- Disconnect the AC power supplies.
- Disconnect the DC disconnection switches.
- Make sure the cable is fixed in position securely.
- Make sure the system cannot be restarted.
- Make sure the electricity supply (AC and DC voltages) has been disconnected.
- Cover or separate nearby live device units.
DANGER! RISK OF ELECTRIC SHOCK!
After disconnecting all power sources wait approx. 5 minutes for the complete discharge of the
unit.
CAUTION! RISK OF BURNS!: During operation the casing can reach high temperatures. Do not
touch the surfaces!

3. FOREWORD
Energy storage is the key solution to meeting the challenges of energy transition, using renewable energy and provid-
ing energy cost reductions for the following 4 main applications.
• Behind-the-Meter Energy Storage:
Reduce peak consumption and maximise PV energy self-consumption. SUNSYS PCS² (IM) can limit the impact
of increases in the electricity retail price by supplying the load to cut peak demand (peak shaving), maximising PV
energy self-consumption at building or community level. Any PV energy surplus is stored in the SUNSYS PCS² (IM)
battery system. This stored energy is used later to supply the load.
1
• PV plants:
Manage the intermittence of renewable energy production. SUNSYS PCS2(IM) ensures the production profile of an
intermittent renewable energy plant by limiting production to a predefined value, injecting energy to compensate for
solar variations, setting constant ramp-up or ramp-down.
2

10 EN SUNSYS PCS2 Power Conversion System and Storage from 33 to 200 kVA - Ref.: IOMSUNPCXX04-EN 01
• Grid support:
Meet the challenge of demand-response energy balance. When directly connected to the grid, SUNSYS PCS2(IM)
improves stability and management of grid operators thanks to voltage and frequency regulation, load shifting, peak
shaving and ancillary services for grid support.
3
• Microgrids:
Ensure energy availability and quality. The SUNSYS PCS² IM enables the microgrid to disconnect from the main grid
and be electrically autonomous thanks to local generation (PV, Wind, Diesel generators, etc.).
